JOSEPH E. MOONEY, OF BALTIMORE, MARYLAND.

SELF-CLOSING VALVE FOR FAUCETS.

SPECIFICATION forming part of Letters Patent No. 252,790, dated January24 1882.

Application filed May 24, 1881.

To all whom it may concern:

Be it known that I, JOSEPH E. MOONEY, a citizen of the United States ofAmerica, residing at Baltimore, in the county of Baltimore and State ofMaryland, have invented certain new and useful Improvements inSelf-Closing Valves for Faucets; and I do hereby declare the followingto be a full, clear, and exact description of the invention, suth aswill enable others skilled in the art to whichit appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

This invention relates to improvemtnts in that class of faucets andsimilar articles wherein are used automaticclosing valves; and itsobject is to provide a faucet actuated in stopping the flow by theutilization of the pressure of the liquid on the piston-head above thevalve or above the valve-seat.

My invention consists in a faucet provided with a piston-head and valveclosed by liquidpressure applied through an induction-way opening in achamber above the piston-head.

My invention further consists in the novel construction and combinationof the parts, as will be hereinafter more fully sr-t forth andspecifically claimed.

Figure l is a longitudinal sectional view, and Fig. 2 is a sectionalview taken through line mof Fig. 1.

The letter Arepresents my improved faucet, consisting of the bit A, tailA vertical chamber or cylinder B, the cap 0, induction-wayD, valve-seatE, formed withthe port F, and the eduction-way Gr.

The chamber B is cast annular and subsequently bored to a true circle,in order that prompt and unimpeded action of the pistonhead may besecured. It is made of smaller diameter than the head of the faucet forthe purpose of forming between its wall and the wall of the faucet theeduction-way G. In this chamber is fitted the piston -rod (1, providedwith the head I), suitably packed, and having the rod extending beyondthe head, and formed with the valve 0. The faucet is covered with thecap 0, which is screwed over the head of (N0 model.)

the faucet and formed with a hole in the center to admit the piston-rod.On the under side of this cap is fitted rubber packing d, which sets onthe top of the walls of the head of the faucet, and is formed with thedownward-extending lips e, which are pressed against the rod by theirown compression, aided by the action of the water. The cap, beingscrewed down to its place, clamps the packing tight between its'lip andthe top of the wall ofthe head of the faucet, and thus-secures it firmlyin place. 4

The upward movement of the piston is effected by pressure on a lever, H,suitably fixed to the projecting end of the piston-rod and cap of thefaucet. To further prevent the escape of water through the hole in thecap the piston-rod has bushing fitted around it atf.

The induction-way D, leading into the cylinder B,extends around thechamber until the wall of the faucet intercepts and combines with thewall of the cylinder at the front of the faucet, where they areidentical. In other words, the passage-way D is eccentric to the chamberB, as seen in Fig. 20f the drawings. The base of the chamber or cylinderB forms the seat E for the valve, and is formed with the port F,substantially as shown in the drawings. (See Fig. 2 This portis madesmaller in its diameter than the diameter of the chamber or cylinder, inorder that the liquid-pressure on the piston-head in the latter mayprevail after the power is removed from the lever and then retain thevalve on its seat when closed.
